When last we saw [xoreaxeax], he had built a lens-less optical microscope that deduced the structure of a sample by recording the diffraction patterns formed by shining a laser beam through it. At the ...

Making a perfect lens that produces flawless images has been a dream of lens makers for centuries. In 1873, Ernst Abbe discovered a fundamental 'diffraction limit' in optics: whenever an object is ...

X-ray diffraction methods lie at the foundation of materials science. Determination of the crystal structures of natural minerals and, later, of crystals grown in the laboratory led to our ...

Simulation games aren't just the realm of thousand-dollar joystick setups and force feedback racing chairs; they can encompass anything, really, from cleaning stubborn dirt to designing the most ...
